Trouble in Terrorist Town v060210

- Equipment weapons dropped by traitors or detectives is
no longer picked up when you are nearby, unless you press the USE key
(ie. it's not automatic anymore).

- Changed Karma indicator
colour scheme to be different from health.

- "Reflection" search
result is only shown when detective searches the corpse. Other players
can still see it on the scoreboard after a detective does this.

-
Detectives now no longer get a credit reward for killing a traitor, but
the entire Detective "team" is awarded a credit if one of them searches
a traitor corpse that had not been searched by a detective before.

-
Detective selection now makes players with low karma (below
ttt_detective_karma_min) less likely to become detective (as if they
were detective/traitor last round).
